Abstract

Novel system for applying surgical clips consisting of an instrument and disposable cartridge that together create a forceps with the cartridge being quickly detachable from the instrument to permit easy and fast replacement during a surgical procedure. The instrument has ring handles as a forceps and they operate to reciprocate a driver. The cartridge includes clinching jaws and a clip magazine with the jaws quick detachably connected to the instrument in a fixed manner whereas an actuator for the jaws is quick detachably fixed to the reciprocal driver of the instrument. A number of surgical clips can quickly and successively be supplied to the clinching jaws of the cartridge.
